Question 1

What are the 5 advantages of offshore wind turbines?

Answer 1

1. Renewable (energy source)
2. Low running costs
3. Energy is free
4. No gas emissions
5. Land is not used (up)

Question 2

What are the 7 disadvantages of offshore wind turbines?

Answer 2

1. Unreliable
2. Hazard to birds/ bats
3. Visual pollution
4. Difficulty of linking turbines to the National Grid
5. Large initial cost
6. Difficult to erect/ maintain
7. CO2 emissions in manufacture (of large number of wind turbines)

Question 3

What are 3 ‘acceptable’ advantages of offshore wind turbines?

Answer 3

1. Named gas (e.g. CO2) emitted
2. No fuel burned
3. Less dependent on fossil fuels

Question 4

What are 2 ‘acceptable’ disadvantages of offshore wind turbines?

Answer 4

1. Wind doesn’t blow

2. A lot of maintenance needed

Question 5

What are 4 ‘unacceptable’ disadvantages of offshore wind turbines (they will be ignored by examiners)?

Answer 5

1. Noise pollution (they’re in the middle of the sea come on)
2. References to destroying or harming habitats
3. Visual pollution- if clearly referring to onshore wind turbines
4. Spoils landscape (see 1st parenthesis)

Question 6

What are the 7 advantages of a cable being lade between Iceland and Britain?

Answer 6

1. Income for Iceland
2. Using Iceland’s (available) energy (resources)
3. Provide electricity when wind does not blow/ reliable
4. Provide electricity at peak times of demand
5. Even out fluctuations in supply
6. Excess electricity from Britain (on windy days) to Iceland and used to pump up water to store energy
7. Britain less dependent on fossil fuels

Question 7

What are the 2 ‘acceptable’ advantage of a cable being lade between Iceland and Britain?

Answer 7

1. Using up (Iceland’s) renewable energy (resources)

2. Conserves fossil fuels

Question 8

What are the 2 ‘unacceptable’ advantage of a cable being lade between Iceland and Britain (will be ignored by examiners)?

Answer 8

1. Reduce the amount of Iceland’s wasted energy

2. Difficult to repair (if damaged)

Question 9

What are the 3 disadvantages of a cable being lade between Iceland and Britain?

Answer 9

1. Large initial cost
2. Power loss along a long cable
3. (Engineering) difficulties in laying/ maintaining the cable
